Some fairly high end Vitus Audio stuff, along with some of that weird Entreq stuff, high end TelluriumQ cabling & matching Focal speakers.
No idea what the Entreq stuff does, if anything or whether the TQ cables were so much better than normally priced wires.
But.....
Something was making some incredible music. No fatigue, just effortless music from the lowest bass to the sweetest treble & imaging which made the system disappear.
Way out of my price range but a very enjoyable experience. I’ve heard other big-rig setups, but this just worked.
